Fit isn’t 100% but they do work and look pretty good.
The fit isn’t 100% it about a 90%. The light bulb doesn’t click and lock into place but not so loose that the bulb comes out, I’ve driven just a little serious with these on and they have held up. Moral of the story. Its definitely aftermarket and you get what you paid for but for what it is im pretty dang happy with them and maybe you will too. It does the job pretty well.

Great brightness and easy installation
Size: H13/9008
I recently installed these AUXITO LED lights on my truck and I’m very impressed with the performance. The brightness is excellent and they make a big difference when driving at night or on dark trails. Installation was straightforward and didn’t take much time. The lights feel well built and look great once installed. Overall, they are a great upgrade if you’re looking for brighter and more reliable lighting.
